Question

我正在尝试配置我的播放框架应用程序，以便它在运行时使用mysql数据库，并在内存数据库中进行测试。当我运行测试时，它连接到mysql数据库而不是内存数据库。谁知道为什么？

这是我的配置：

db.default.driver=com.mysql.jdbc.Driver
db.default.url="jdbc:mysql://localhost/communityRoots?characterEncoding=UTF-8"
db.default.user=root
db.default.password= ""

db.test.driver=org.h2.Driver
db.test.url="jdbc:h2:mem:play;MODE=MYSQL"
db.test.user=sa
db.test.password=""

这是我的测试：

running(fakeApplication(inMemoryDatabase("test")), new Runnable() {
        public void run() {
            new User("bob@gmail.com", "Bob", "secret").save();
            assertNotNull(User.authenticate("bob@gmail.com", "secret"));
            assertNull(User.authenticate("bob@gmail.com", "badpassword"));
            assertNull(User.authenticate("tom@gmail.com", "secret"));
        }
    });

从我正在开发的实际应用程序：

import play.api.inject.bind
import org.scalatest.mock.MockitoSugar
import play.api.Application
import play.api.inject.guice.GuiceApplicationBuilder
import database.AccountDAO
import play.api.Configuration
import play.api.Mode


class AccountDAOSpec extends Specification with MockitoSugar { // we add mockito to show that you can also bind your mocks


val companyAccountDAOMock = mock[CompanyAccountDAO] // let us create a company account DAO mock

  def app = new GuiceApplicationBuilder() // you create your app
    .configure(
      Configuration.from(
        Map( // a custom configuration for your tests only
          "slick.dbs.default.driver" -> "slick.driver.H2Driver$",
          "slick.dbs.default.db.driver" -> "org.h2.Driver",
          "slick.dbs.default.db.connectionPool" -> "disabled",
          "slick.dbs.default.db.keepAliveConnection" -> "true",
          "slick.dbs.default.db.url" -> "jdbc:h2:mem:test",
          "slick.dbs.default.db.user" -> "sa",
          "slick.dbs.default.db.password" -> "")))
    .bindings(bind[AccountDAO].to[AccountDAOImpl]) // here you can define your bindings for an actual implementation (note the use of square brackets)
    .bindings(bind[CompanyAccountDAO].to(companyAccountDAOMock)) // or bind to your mock (note the use of parentheses)
    .in(Mode.Test)
    .build()


  "AccountDAO" should {

    "throw an Exception when adding a user with an invalid data" in new WithApplication(app) { // here you can use the application you just created, it uses the db you defined for your tests

      val app2dao = Application.instanceCache[AccountDAO]
      val accountDAO = app2dao(app) // with this you get the DAO injected

      accountDAO.addAccount(testAccount).run must throwAn[Exception] 
    }
  }
}

您应该删除“测试”。因此，您的第一行应该是：

running(fakeApplication(inMemoryDatabase()), new Runnable() { 
    //test specific code
});

播放框架在内存中使用h2数据库进行单元测试
